Book Description
This book focuses on Nuclear-Pumped Laser (NPL) technology and provides the reader with a fundamental understanding of NPLs, a review of research in the field and exploration of large scale NPL system design and applications. Early chapters look at the fundamental properties of lasers, nuclear-pumping and nuclear reactions that may be used as drivers for nuclear-pumped lasers. The book goes on to explore the efficient transport of energy from the ionizing radiation to the laser medium and then the operational characteristics of existing nuclear-pumped lasers. Models based on Mathematica, explanations and a tutorial all assist the reader’s understanding of this technology. Later chapters consider the integration of the various systems involved in NPLs and the ways in which they can be used, including beyond the military agenda. As readers will discover, there are significant humanitarian applications for high energy/power lasers, such as deflecting asteroids, space propulsion, power transmission and mining. This book will appeal to graduate students and scholars across diverse disciplines, including nuclear engineering, laser physics, quantum electronics, gaseous electronics, optics, photonics, space systems engineering, materials, thermodynamics, chemistry and physics.

Book Description
The first direct nuclear pumped laser to operate on a visible wavelength is described, whereas previous nuclear lasers have operated in the infrared. The Sandia Pulsed Reactor II was used as a high flux source of neutrons that pumped a helium-mercury gas laser via the high energy products of the /sup 10/B(n, .cap alpha.)/sup 7/Li nuclear reaction. No other source of energy was utilized. Lasing was observed at 6150 A, corresponding to the 7/sup 2/P/sub 3/2/--7/sup 2/S/sub /sup 1///sub 2// mercury ion transition. The thermal neutron flux threshold for lasing was approximately 1 x 10/sup 16/n/cm/sup 2/-sec, and the laser output was continuous over the 400 .mu.sec operating time of the nuclear reactor. The laser signal appeared to increase linearly with the thermal neutron flux, up to 5.8 x 10/sup 16/n/cm/sup 2/-sec, the highest flux used.

Book Description
The present political and environmental climate may slow the inevitable direct utilization of nuclear power in space. In the meantime, there is another approach for using nuclear energy for space power. That approach is to let nuclear energy generate a laser beam in a ground-based nuclear reactor-pumped laser (RPL), and then beam the optical energy into space. Potential space applications for a ground-based RPL include (1) illuminating geosynchronous communication satellites in the earths̀ shadow to extend their lives, (2) beaming power to orbital transfer vehicles, (3) providing power (from earth) to a lunar base during the long lunar night, and (4) removing space debris. FALCON is a high-power, steady-state, nuclear reactor-pumped laser (RPL) concept that is being developed by the Department of Energy with Sandia National Laboratories as the lead laboratory. The FALCON program has experimentally demonstrated reactor-pumped lasing in various mixtures of xenon, argon, neon, and helium at wavelengths of 0.585, 0.703, 0.725, 1.271, 1.733, 1.792, 2.032, 2.63, 2.65, and 3.37?m with intrinsic efficiency as high as 2.5%. Frequency-doubling the 1.733-?m line would yield a good match for photovoltaic arrays at 0.867?m. Preliminary designs of an RPL suitable for power beaming have been completed. The MWclass laser is fairly simple in construction, self-powered, closed-cycle (no exhaust gases), and modular. This paper describes the FALCON program accomplishments and power-beaming applications.

Book Description
There is provided a direct nuclear pumped gas laser in which the lasing mechanism is collisional radiated recombination of ions. The gas laser active medium is a mixture of the gases, with one example being neon and nitrogen.
